The Legend of the Immortal Cauldron

He had seen many pill formulas, and with his knowledge, he could easily judge the authenticity of the pill formula.

The pill formula of the Ningying Pill in his hand was indeed real.

"The pill formula is correct. I wonder how many pills you want to exchange." Matthew asked calmly after returning the tortoise shell to the other party.

"Just exchange it for ten top-grade white jade pills in your hand." The man did not mean to ask for too much.

Considering the value of the pill formula, it is reasonable to exchange it for ten top-grade white jade pills.

"I want something else from you." Matthew suddenly turned his eyes and said.

"What do you want?" The man asked in confusion.

He only took out a pill formula, and he didn't know what else Matthew wanted.

"I have a hobby. I like to collect all kinds of masks. I like your mask." Matthew chuckled.

"This is just a mid-grade magic weapon. Do you want it too?" The man pointed to his mask and asked in confusion.

"It doesn't matter what the grade is. I just like to collect these weird things." Matthew laughed.

"No problem, I'll give you this mask."

After saying that, the man turned around and took out another mask from the storage bag.

Although the man would not believe Matthew's words, he had worn this mask for many years and knew that it was just an ordinary medium-grade magic weapon.

Although he was a little confused, in order to get the top-grade white jade pill, what was a mere medium-grade magic weapon.

After changing the mask on his face and putting on a new mask, he turned around again.

Putting the tortoise shell and the mask together, Matthew used his magic power to drag the two jade bottles to float in front of the other party.

After the two quickly collected the things they needed, Matthew removed the shield and returned to the original position.

Originally, he was going to take action against this person after the exchange meeting was over.

Now it's good, since he got the mask so smoothly.

In addition, there is also a recipe for the Ningying Pill.

This made him feel very happy.

After a few hours, the underground exchange meeting was also coming to an end.

Finally, the monk with black air all over his body represented the exchange meeting and took out ten things to exchange with everyone.

It was different from the auction where items were taken out one by one.

This person took out all ten items at once, and only said the names of the items without introducing their functions.

Some of the items were the first time Matthew had heard the names of.

Even the Spiritual Venerable didn't know what those items were used for.

Just because Matthew didn't know didn't mean that others didn't know.

Soon, several people came on stage and successfully exchanged the items he didn't recognize.

After one person left the stage, Matthew also walked on stage.

"What do you want to exchange this piece of thick earth essence for?" Matthew pointed to the largest item on the stage and asked in a voice transmission.

"If you have a top-grade Yangxin Pill, you can exchange it for this." The cultivator in the black air obviously remembered Matthew and said in a very kind tone.

"I'm afraid you have some misunderstandings about me. Top-grade Yangxin Pills are such precious things. I only have three mid-grade Yangxin Pills." Matthew shook his head and replied.

He was telling the truth this time. Yangxin Pills are a very magical auxiliary pill.

It is a special medicine used to resist the inner demon.

Although Matthew had refined some, due to material problems, all of them were inferior.

After being purified by the purple cauldron, it became a medium-grade one.

"It's medium-grade, so three medium-grade Yangxin Pills in exchange for this piece of thick earth essence."

Although the monk in the black air said it reluctantly, there was a hint of joy in his voice.

Matthew knew that the other party had deliberately asked for a high-grade Yangxin Pill before.

In order to test whether he had a Yangxin Pill.

But since Matthew chose to go on stage, he was already prepared.

It was just three medium-grade Yangxin Pills, so he would not be stingy.

After exchanging the thick earth essence from the black air monk, Matthew left the exchange directly.

Although there were still a few things, he was not interested.

Through the teleportation seal, Matthew left the underground exchange.

After appearing at a location on the island, Matthew immediately flew towards Wangyue City.

This trip was fruitful, and he needed to deal with the things at hand as soon as possible.

After returning to the inn, Matthew immediately took out the thick earth essence he had exchanged.

Let the cauldron spirit connect to the tree spirit in the purple cauldron.

"I have found the thick earth essence you want, it's time to give me the treasure of the sea monsters." Matthew said lightly.

"Of course there is no problem, I will give it to you now." The tree spirit immediately spoke after seeing the thick earth essence beside Matthew.

A purple light flashed, and a section of gray roots appeared in front of Matthew.

There was a blue on this root.

Inside was the treasure of the sea monsters.

"I have cut off the root of my life, you just need to take out the things inside." The tree spirit said softly.

Matthew nodded when he heard the words, and the purple light flashed in his hand, and the thick earth essence disappeared.

This was the agreement he had reached with the tree spirit before.

The other party was willing to give him the treasure of the sea monsters only if he found the thick earth essence.

After the thick earth essence disappeared, Matthew waved his hand, and a ball of golden light appeared and wrapped the tree spirit's life roots.

What he had to do now was to take out the Siren Clan's treasure that was fused with the life roots.

He was also quite curious about this treasure.
